TRUSS.

SPECIFICATION forming part of Letters Patent No. 752,445, dated February16, 1904.

Application filed August 5,1903.

To all whmn it may concern:

Be it known that I, DANIEL T. FOLEY, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented new and useful Improvements in Trusses, of which thefollowing is a specification.

My invention consists of a truss for hernia or rupture in which thepressure of the pad may be adjusted in a simple and convenient manner,the means employed beinghereinafter set forth and the novel featuresthereof pointed out in the claim.

Figures 1 and 3 represent perspective views of portions of a trussembodying myinvention. Fig. 2 represents a section on line 02 m, Fig. 1.Fig. 4 represents a perspective view of a detached portion.

Similar letters of reference indicate corresponding parts "in thefigures.

Referring to the drawings, Adesignates the,

I body-spring of a truss, and B designates a pad connected with the endthereof. Projecting from and firmly secured to said spring are the screwO and T-headed stud D, said screw being adjacent to said pad and saidstud being removed a certain distance therefrom.

E designates an auxiliary spring, which is composed of a bar or plate ofresilient material, the same having at opposite ends the slots Gr and N,which are adapted to receive, respectively, the screw O and T-headedstud D, it being noticed that the slot Gr may be passed over the flat orangular head of said stud, and then by a quarter-turn of the spring Ethe shankof said stud occupies said slot G, while the upper and lowerwalls of the latter are between said head, thus connecting the adjacentend of the spring E with the spring A. Then the said spring E is pressedtoward or against said spring A and the slot F caused to receive thescrew 0, after which a nut H is applied to said screw and tightenedagainst the spring E, whereby the end of the latter next to the pad isconnected with the spring A, the spring E thus being retained in posi-Serial No. 168,274. (No model.)

tion on the truss as such in the direction of the length of the latter,both practically as one, it being seen that there is now a duplicationof springs, whereby the spring A proper is stiffened and made lessresilient in action, and so exerts a greater pressure on the pad andconsequently on the place of rupture. Owing to the slots F G, the springE may have a certain play on the latter during the bending of bothsprings, thus preventing binding of the same one on the other. Shouldfurther pressure. be desired, another spring, such as E, may be appliedand secured similar to to the latter.

.When normal pressure is desired, the spring E may be removed byunscrewing the nut H, withdrawing the spring from the screw C, and thenturning said spring so that the slot Gr thereof registers with the flator narrow head of the stud D, when the spring may be slipped from thelatter. This leaves the spring A bare of the spring E, as in Fig. 3, theeffect of which is evident.v

It will be seen that as occasion arises the wearer of the truss mayincrease the pressure of the pad or decrease the same, either at thedesired place, without necessarily having the services of an expertattendant, providing a plurality of trusses of different degrees ofpressure, or disturbing the primary resiliency of the spring A.

The use of the stud D as a form of retainer for the adjacent end of thespring E is pre ferred, as it aifords a convenient means for attachingsaid end to the spring E and admits of the employment of a single screwand nut for preventing separation of the outer spring.

Various changes maybe made in the details of construction shown withoutdeparting from the general spirit of my invention, and I do not,therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A truss comprising a body-spring, a pad sespring and have limitedlongitudinal movement.

DANIEL 'r. FOLEY.
